GPS Tracking Applications
Tracking applications allow users to share information generated by GPS in their mobile devices about the paths they use to travel. These data are an excellent source of planning information because they show paths really taken by users and can provide real time information about speeds or performance conditions. Many tracking applications allow users to add information to maps such as problems.
Waze is the most familiar tracking application. It tracks users to identify real time roadway traffic conditions and allows users to enter data (e.g., accident locations). Waze is combined with a travel planner that provides users on fastest routes given real time traffic conditions.
Tracking applications have also been developed for sustainable transport modes: public transport, biking and walking. Fitness applications are an especially good source of information on biking and walking.
Cities are increasingly using (buying) data from tracking applications developed by private companies. For example, many cities are working with Waze to obtain traffic data and with fitness application developers like Strada to obtain bicycling data. In some cases cities have developed partnership programs where they provide certain data to the developers and the developers provide data to the city in return. See The Social Network That Helps Planners Understand Pedestrians and Cyclists from CityLab (Nov 2017) for more.
Agencies planning to use tracking data need to consider:
- Data privacy?
- Should agencies buy data from commercial app developers or develop their own apps?
- Are application users typical (i.e. not competitive bike riders)?
- Should cities plan for typical app users?
The next sections outline tracking data applications for sustainable transport modes.
Examples: GPS Tracking Apps

Meine Radspur is an early example of using GPS tracking for bicycle planning.
Bicycle Tracking Apps
Bicycle tracking applications are one of the most popular types of GPS tracking applications. In addition to many privately developed fitness tracking applications many cities and researchers have created these applications individually. Given the large number of applications we’ve created a special page with example bicycle tracking data applications and references:
Public Transport Tracking Apps
Public transport is another field where many GPS tracking applications have been developed. In this case there seem to be more private-sector developed applications than in the case of bicycle GPS tracking applications.
In 2017 London did an experiment to anonymously track passengers to learn about travel patterns (see Rachel Dovey in Next City: What a London transit agency learned from tracking riders for a month (Feb 2017).
Here’s a link to our page with example public transport GPS tracking applications and references:
Pedestrian Tracking Apps
Interestingly, aside from pedestrian tracking that’s part of fitness applications there do not seem to be very many applications directly created to provide planning data from pedestrian trips. Probably I’ve missed some, but it could be a good market to explore.
Open Source Vehicle Tracking
Mapzen has developed the Open Traffic platform in conjunction with the World Bank. The platform uses anonymous GPS location data to develop roadway speed information. It’s available on GitHub. The Mapzen blog post Open Traffic platform released provides detailed information and references.

MetroQuest Collaboration Application
MetroQuest is an application that provides a suite of tools that can be used to improve the public participation process. The tools support all three types of collaboration: engagement, education and process. It’s been used for many transport projects including Toronto’s Big Move 25-year transportation plan.

Transit App adds Real Time Information
The Transit App can now collect tracking data from users to help them predict real time arrival information. This is an excellent tool especially in cities where there is no current real time data available. It’s also quite helpful because it can be more accurate than vehicle GPS signals since these signals may only be sent […]

Making Sense Project
The Making Sense project is funded by the European Commission and has the mission to make advances and experiments in participatory sensing. According to making-sense.eu Making Sense aims to explore how open source software, open source hardware, digital maker practices and open design can be effectively used by local communities to fabricate their own sensing tools, […]

City Swipe – Santa Monica Downtown
City Swipe is a Tinder-like application designed to collect input on what people like and dislike about downtown Santa Monica (California). It’s really simple to use and therefore good for collecting lots of input. Here are the instructions from the project website: www.dtsmcityswipe.com HERE’S HOW IT WORKS Each slide will show an image and a […]
